Superimposing architectural models onto street photographs
If you want to place your models so they look like they are part of a photograph, you should be looking for VFX (video effects) tutorials.
CG Geek has a few on YouTube, where he adds objects to video footage, but the same techniques apply for still photographs.
Blender Guru has some too.  Try searching for "How to render onto a photo background" on his website.
